Interdimensional Traveler

You continue walking into the evening, hoping to find some trace of civilization. You are frightened but you also want to find out what happened here and if there is anything left. It is especially creepy that there are no street lights in this part of the city. But you can see some about a mile ahead, at least it looks like it is about a mile...you also see what looks like a pair of headlights coming from behind you. They appear to be about two miles away. You will not be able to make it to the city lights before the car gets here. You have about five minutes to decide whether the driver is friendly or not...
